Product Introduction & Application
GB U71Mn rails commonly used in port cranes include QU70, QU80, QU100, QU120, etc. The number after QU indicates the width of the rail head.
U71Mn rails are high-carbon non-alloy steels with a high carbon content, generally around 0.65%-0.76%, and contain a certain amount of manganese, usually 1.10%-1.50%. This composition design makes the rails have high strength and hardness, and can withstand the huge pressure and impact force of the port crane trolley and car during operation. At the same time, U71Mn rails also have good wear resistance and certain toughness, which can resist the long-term rolling and wear of wheels, prevent brittle fracture, and ensure the safe operation of cranes.

Product Application
Mainly used in the trolley and car tracks of port cranes to provide stable support and guidance for the operation of the cranes. Since port cranes need to load and unload goods frequently, the bearing capacity and wear resistance of the tracks are required to be high. U71Mn rails can meet these requirements well and ensure the efficient operation and long-term stable use of cranes.
